Configure SMS gateway

This section describes how to configure an SMS gateway for the Onegini Token Server. Since we have different options of SMS gateway implementations you need to
make a choice which one suits you best. The different options are described below.

REST-based SMS gateway

The most flexible way to allow the Token Server to send SMS messages is by implementing your own (micro) service based on the REST API that the Token Server invokes.
This service can either be a small component that translates our API to a vendor specific API or it can be a middleware layer which already has access to a generic message gateway.

The REST API that the Token Server uses in case the REST SMS gateway is activated is described in the API specification.
